Definitions

  • This invention relates to a parting or grooving insert, according to the preamble of claim 1 and as known for example from EP-A-0365299 .
  • Such parting or grooving inserts of the kind to which the present invention particularly relates are formed with a front cutting edge which is inclined with respect to a normal to a longitudinal median plane of the insert by an angle known as the lead angle of the insert.
  • Such inserts are generally divided into three categories, namely right-hand and left-hand inserts depending on the direction of inclination of the insert and neutral inserts where the leading angle is substantially zero.
  • the cutting edge is formed at the intersection of an upper rake surface of the insert and a front relief flank thereof.
  • the cutting end portion is formed with a leading angle
  • the relief flank is correspondingly inclined with respect to a normal to a longitudinal median plane of the insert.
  • a double-ended parting or grooving insert comprising a central body portion and a pair of opposite cutting end portions; each cutting end portion having an upper rake surface and front and side relief flanks and a front cutting edge formed at an intersection of said rake surface and said front relief flank; characterized in that said front relief flank comprises an upper relief flank surface component; a lower abutment surface component inset with respect to said upper component and disposed substantially normally with respect to a longitudinal median plane intersecting sad front cutting edges and an intermediate surface component serving to bridge said upper and lower components.
  • Said cutting edge and said upper relief flank surface component are inclined with respect to a normal to said plane by a leading angle of said cutting edge.
  • the double-ended parting or grooving insert in accordance with the invention is of the right-hand or left-hand type where the front cutting edge and the associated upper relief flank component surface have leading angles of respectively opposite senses.
  • the cutting insert can be securely retained in an appropriate insert holder with its abutment surface component abutting over its entire surface area the adjacent support surface of the holder. In this way the same insert holder can be effectively used irrespective of whether the insert is neutral, right-handed or left-handed and at the same time ensure the effective supportive abutment of the insert within the holder.
  • a double-ended parting and grooving insert 1 comprises a central body portion 2 and, a pair of opposite cutting end portions 3a and 3b.
  • Each cutting end portion (3a,3b) comprises a rake surface 4 and a front relief flank 5 and side relief flanks 6.
  • a front cutting edge 7 is formed at the intersection of the rake surface 4 and the front relief flank 5.
  • each front relief flank 5 comprises an upper, relief flank surface component 5a, a lower abutment surface component 5b and an intermediate surface 5c which serves to bridge the respective upper and the lower surface components 5a and 5b. Furthermore, the lower abutment surface component 5b is inset with respect to the upper relief flank surface component 5a.
  • each front cutting edge is inclined with respect to a normal 9 to a longitudinal median plane 10 of the insert by an angle ⁇ known as the leading angle of the insert. Depending on the sense of the angle ⁇ with respect to the normal 9 the Insert can be right-handed or left-handed.
  • the upper relief flank surface component 5a is also inclined with respect to a normal to the longitudinal median axis of the insert by the same leading angle ⁇ .
  • the lower abutment surface component is disposed substantially normally with respect to the longitudinal median plane of the insert.
  • the insert is designed to be retained in an insert holder 12 having an insert retaining slot 13 defined between respective upper and lower clamping surfaces 14 and 15 of an upper, resiliently displaceable clamping jaw 16 and a lower, relatively fixed clamping jaw 17, respectively.
  • An inner rear end of the retaining slot 13 is formed with upper and lower curved recesses 18 and 19 and a central support surface 20.
  • double-ended parting and grooving inserts of the kind just described in accordance with the invention can be readily prepared by compacting of, for example, tungsten carbide powders in a suitable die for subsequent sintering, thereby obviating in many cases the necessity of subsequent grinding operations, it is possible to produce inserts in accordance with the present invention utilizing such grinding operations.
  • An insert such as that shown in Fig. 3 of the drawings which has been prepared by compacting and sintering may be subsequently ground so as to provide a much increased lead angle.
  • Cutting inserts in accordance with the present invention which are, as explained, of the right-handed or left-handed kind can be effectively and securely retained in insert holders which can be used for all types whilst, at the same time ensuring that the rear end of the insert is effectively supported by abutting over a significant surface area the support surface formed by the holder.
  • parting and grooving inserts whose cutting edges have leading angles which range from greater than 0° to 20° can be effectively employed in accordance with the present invention.
